Histopathological assessment of the digestive gland of a freshwater snail (Lymnaea stagnalis) exposed to uranium This dataset consists of measurements of the digestive gland in the freshwater snail Lymnaea stagnalis orally exposed to uranium. The objective of the study was to assess the morphological effects of uranium on the snail digestive gland by light microscopy. Laboratory-cultured L stagnalis were exposed to either synthetic or natural solid phases of uranium and a subset (6 controls and 6 exposed) were euthanized and fixed in 10% neutral buffered formalin for histopathological assessment. Slides were processed and stained with hematoxalin and eosin as per standard procedure (Luna 1968). The size of each sample, the length and width of digestive gland tubules (5 random glands per sample) and height of digestive cells...

Briefly, our research group previously developed a recombinant RCN vaccine candidate expressing a mosaic glycoprotein (MoG) gene that protected mice and big brown bats when challenged with rabies virus (RABV). We developed two new recombinant RCN candidates expressing MoG (RCN-tPA-MoG and RCN-SS-TD-MoG) with the aim of improving RCN-MoG. We assessed and compared in vitro expression, in vivo immunogenicity, and protective efficacy in vaccinated mice challenged intracerebrally with RABV. In this data set, we share results of immunofluorescence assay...

While their contribution to trophic linkages and dynamics in coral reef systems has received considerable attention, the role of linkages involving their parasites has not. As both consumers of fish tissue and prey to microcarnivores, external parasites can play a significant role in trophic transfer between the primarily algae-based food source and the broader coral reef community. Stable isotope analysis is a common tool for studying trophic linkages, which can be used for studies involving parasites. These data were collected to examine the stable isotope ecology (13C and 15N) of copepod (Caligus atromaculatus) and...

Polygons were created adjacent to either side of the flight lines (transects). The right and left offset of the polygons from the flight path, was determined using the average altitude of the plane along the transect and the observation angle through the plane’s window. Observed birds were counted and identified by species. This count data was attributed to the polygon closest to the point along the transect where the observation occurred, and on the side of the plane in which the observation took place. The point data represent counts where each point represents a single species....

However, a lack of historical disease data has made it challenging to determine whether Oo is a recent arrival to the USA or whether SFD emergence is due to other factors. Here, we examined the genomes of 82 Oo strains to determine the pathogen’s history in the eastern USA. This dataset contains metadata on the strains used in that study.

The files are in FASTQ format as exported from the Oxford Nanopore’s MK1C using MinION flowcells. Files are labeled according to the method (as described in the paper) and the Sample ID). The MK1C exports data in blocks of 6000 reads per FASTQ file and all the FASTQ files from each method and sample are grouped in a common folder.

Carcasses of bald eagles (n = 172) and golden eagles (n = 142) collected from North and South Dakota, Montana, Wyoming, Colorado, Utah, Nebraska, and Kansas between 2014-2017 were assessed for cause of death and liver lead, mercury, and AR levels.

Utah prairie dogs were live-trapped and sampled on 5 colonies. We recorded the age (juvenile/adult) and mass (nearest 5 grams) of each prairie dog and marked its ears and body with metal tags and passive integrated transponders, respectively, for permanent identification. We measured each prairie dog's right hind foot length (nearest millimeter). We indexed each adult prairie dog's body condition as the ratio between its mass and hind-foot length. Prairie dogs were allowed to recover from anesthesia and released at their trapping locations. We indexed prairie dog reproduction, by colony...

However, more focused surveillance efforts identified the presence of disease hot spots occurring among juvenile life history stages from certain nearshore habitats. These outbreaks sometimes recurred annually in the same temporal and spatial patterns and were characterized by infection prevalence as high as 96%. Longitudinal sampling indicated that some epizootics were relatively transient, represented by positive samples on a single sampling date, and others...

We sampled prairie dogs at Conata Basin, Buffalo Gap National Grassland, and Badlands National Park, South Dakota, USA. We sampled fleas from live-trapped prairie dogs during June–October 2018, May–October 2019, and July-August 2020. Prairie dogs were sampled before and after FipBit treatments. We anesthetized each prairie dog with isoflurane and combed it thoroughly for 30 seconds to dislodge fleas, which fell into a plastic bin. Fleas were counted and allowed to recover from anesthesia and placed back on prairie dogs, to minimize any removal effect. We weighed prairie dogs with...

Studies on the histopathology of American pikas are limited. This report summarizes the clinical histories, and gross and histologic findings of 12 American pikas, including nine captive and three wild animals. Death was often attributed to stress (transport, handling, and anesthesia) with few to no premonitory clinical signs. Two cases died due to infection: one had bacterial pyogranulomatous dermatitis, cellulitis, and lymphadenitis with sepsis; the other case had fungal necrotizing colitis. Incidental parasite infections included sarcocystosis, nematodiasis (oxyurids), and ectoparasitism. Most...

Control birds were challenged with vehicle only or vehicle and poly I:C. At euthanasia, spleen, thymus, and bursa of Fabricius were collected and fixed in 10% neutral buffered formalin for histopathological assessment.

Quantification of parasites are important to understand epidemiology of spirorchiid infections in sea turtles, however different methodologies for quantifying Spirorchiidae eggs in turtle tissues have been used. The most representative way to quantify Spirorchiidae burdens in tissues is counting eggs / g of tissue, however, this method is very laborious. As an alternative, we propose quantifying number of Spirorchiidae egg/ area of tissue on a microscope slide. We compared this method to number of eggs / slide, a common metric of egg burden in turtle tissues. Both methods correlated well with eggs / g with eggs/mm2...

As part of the trial, tri-colored bats (Perimyotis subflavus) were exposed to Pseudogymnoascus destructans (Pd) and allowed to hibernate in chambers with a variety of temperature and humidity conditions. Bats were euthanized after 83 days. A portion of the wing was rolled around dental wax dowels, fixed in 10% neutral buffered formalin, processed and stained with periodic acid-Schiff, and assessed by light microscopy for evidence of fungal infection.

Assays were tested on fish tissue and on field-collected water samples to assess diagnostic and environmental DNA capabilities. The specificity, sensitivity, and broad applicability of the present assays surpass previous methods for detecting T. bryosalmonae DNA from fish tissue and water samples.

The datasets included here contain information on individual toad capture history, body size, and disease status. These data were collected annually over the 16-year period at up to 11 breeding sites per year on the refuge. We include datasets for (1) male toad captures over time, (2) female toad captures over time, (3) male disease status (tested - positive or negative, or not tested in a given year), (4) all toad length and weight data over time, and (5) male toad size and body condition over time.
